Exploring System 1 and 2 communication for latent reasoning in LLMs

Julian Coda-Forno, Zhuokai Zhao, Qiang Zhang +6

Should LLM reasoning live in a separate module, or within a single model's forward pass and representational space? We study dual-architecture latent reasoning, where a fluent Base…
